Hello, our valued customer. Our product, "Women's Front Tie Tunic Burgundy," is offered in two different size options: S/M (size 36-38) and L/XL (size 40-42). Depending on your height and weight, you may think that size S/M may be suitable. However, if you prefer a more comfortable fit, you can also consider the L/XL size, considering that the product's fit is "Regular". To ensure a more accurate fit, we recommend comparing the measurements (shoulder, chest, and waist) listed in the product description with your own measurements. 😊 We wish you pleasant shopping!
